Abstract: A foot-controlled water tap for regulating the outflow of water from a water tap by means of air pressure comprises a bladder 1 connected to an air bellows 81 within the water tap by a passageway 3, a valve block 86, a ring body 67 and a knob 52 forming the water tap. When the bladder 1 is stepped upon by foot the air inside is compressed and sgueezed through the passageway 3 to the bellows 81 which expands and pushes a platform 35 downwards. The platform 35 is fixed to a stem 18 mounted within the ring body 67 and the valve block 86 and thus the stem 18 also moves downwards and away from the opening of the valve block 86 through which water flows allowing water to flow through the valve block 86. Water is stopped by releasing the pressure applied to the bladder 1 which allows the restoring force of a spring 17 to push the platform 35 and hence the stem 18 upwards moving the stem 18 back to its original position and forcing air from the bellows 81 through the passageway 3 to the bladder 1. The tap can also be controlled by hand through a knob 52 like an ordinary water tap. A liguid can replace the air in the bladder 1, passageway 3 and bellows 81.

Abstract: Improvement to the method of elemental analysis of a sample by mass spectrometry coupled to a plasma induced by high frequency, by means of an installation including a torch for producing the plasma from a plasma-forming medium and for injecting some of the sample into this plasma and a sample-withdrawal interface, comprising two successive cones arranged on the same axis but having different vertex angles and each provided with an axial orifice for the passage of a fraction of the sample to be analysed. According to the invention, a given quantity of a make-up gas, with high calorific value, is added to the sample injected into the plasma, in such a way as to raise the temperature of the plasma in order to locally heat the withdrawal cones so as to preclude the deposition on the latter of the components of the sample which are present in the plasma. Preferably, the withdrawal cones (18, 19) are made from an alloy of niobium, hafnium, titanium. <IMAGE>

Abstract: Dispositif de transport comprenant un réseau de rails à ramifications, sur lequel se déplacent des véhicules autonomes porteurs de pièces, constitués par des wagonnets, ledit réseau présentant une haute sécurité de fonctionnement dans des situations non régulières d'exploitation. On propose, dans ce but, plusieurs dispositifs indépendants qui sont agencés de façon particulièrement avantageuse pour une application commune. Selon une première forme d'exécution, il est prévu une logique d'exploitation des signaux réalisée dans un micro-ordinateur (10) contrôlant la succession, en fonction du temps, des informations de circulation reçues par le wagonnet et des signaux extérieurs, quant à leur plausibilité logique et, le cas échéant, immobilisant le wagonnet. Selon une seconde forme d'exécution, le panneau basculant avant (13) du wagonnet est conçu comme un interrupteur à deux phases, le premier état de connexion (34) étant obtenu pour un léger choc, et le second état de connexion (35), pour un choc dur non régulier. Selon une autre forme d'exécution, le wagonnet présente un détecteur de chocs (24) réagissant en cas de choc dur non régulier. Selon une autre forme d'exécution, il est prévu un dispositif de contrôle de prise d'énergie (40), capable d'enregistrer l'énergie prélevée aux batteries, dans un intervalle de temps T déterminé, et de la comparer avec une valeur limite prédéterminée (46) et d'immobiliser le wagonnet lorsque cette valeur limite (46) est dépassée pendant une longue durée.

Abstract: Un procédé et un appareil pour réduire l'usure d'une électrode dans un chalumeau à arc de plasma consiste à modifier l'écoulement de gaz dans une chambre de plasma entourant l'électrode (22) immédiatement avant et subséquemment de l'arrêt du courant qui soutient l'arc (18). Cette altération consiste à fermer l'écoulement de gaz en amont de la chambre (32), passer d'un écoulement rotationnel à un écoulement radial/axial à travers la chambre de plasma (32), réduire le niveau de courant de l'arc en conjonction avec l'une des deux opérations ci-dessus, et vider la chambre de plasma (32) pour modifier rapidement l'écoulement et la pression de gaz dans la chambre. L'intervalle est suffisant pour réduire l'usure de l'électrode, mais assez court pour que l'arc demeure stable jusqu'à l'arrêt d'écoulement, une électrovanne (48) est placée sur le tube d'entrée (46) du gaz de plasma. L'altération de l'écoulement a aussi lieu au démarrage. Un pré-écoulement de gaz est établi avant allumage d'une veilleuse d'arc. Lorsqu'il est transféré, l'écoulement augmente jusqu'à son niveau de fonctionnement maximal en conjonction avec une augmentation dans le courant de l'arc. Le pré-écoulement peut être axial ou partiellement axial. En outre, le type ou la composition du gaz utilisé dans le pré-écoulement et l'écoulement opérationnel peut changer au cours du démarrage d'un gaz moins réactif à un gaz plus réactif.

Abstract: Système d'actionnement de moteurs à induction qui commande de façon appropriée la vitesse du moteur à induction dans une plage de rotation à vitesse élevée et dont la réactivité à une commande de vitesse est excellente. Des données d'impulsions de glissement (SB) et des données d'impulsions de décalage de phase (FB), qui sont calculées par un processeur (1) en fonction de la commande de vitesse et de la sortie d'un détecteur de vitesse, sont ainsi créées. En fonction de ces données, des impulsions de glissement (SSP) et des impulsions de décalage de phase (FSP) sont sorties d'un circuit (20) servant à générer des impulsions de glissement et d'un circuit (21) servant à générer des impulsions de décalage de phases respectivement. Un compteur (24) compte les impulsions de retour calculées en fonction de la sortie du détecteur de vitesse et les impulsions provenant d'un circuit (23) servant à superposer les impulsions, qui correspondent au résultat de l'addition des impulsions de glissement et des impulsions de retour calculées en fonction de la sortie du détecteur de vitesse, aux impulsions de décalage de phase. Le compteur (24) génère un premier signal de transition (CS1) au moment où le compteur (24) compte le nombre d'impulsions prédéterminé. Un circuit (26) servant à sortir des ondes rectangulaires génère des signaux d'impulsions rectangulaires (Us-W(Boolean not)s) en fonction d'un premier signal de transition (CS1), un second signal de transition (CS2) obtenu en différant le signal (CS1), et des signaux (RS, R(Boolean not)S(Boolean not)) servant à établir une discrimination entre les sens de rotation provenant du circuit (23). Le moteur est actionné et commandé par les signaux d'impulsions rectangulaires tout en fonctionnant à vitesse élevée, ou bien par des signaux PMW (Up-W(Boolean not)p) générés par le processeur à la place des signaux d'impulsions rectangulaires tout en fonctionnant à vitesse faible.

Abstract: Tamis à sable tubulaire (42) constitué par une pièce monobloc entièrement composée de copeaux métalliques en poudre (42A), moulés et frittés pour former une structure tubulaire rigide et compacte métallurgiquement. On agglomère un agrégat de particules métalliques, des copeaux d'acier inoxydable par exemple, par diffusion interatomique résultant du frittage des copeaux agglomérés sous une température et une pression élevées. Le tamis à sable en métal fritté joue le rôle d'un ensemble classique de précompression ainsi que celui d'un filtre. Selon un des aspects de l'invention, on soumet le tamis de métal fritté à une opération d'électro-polissage pour produire une porosité effective de 40-60 mesh, dont les pores (42B) ont une dimension moyenne de 150 microns. On supprime la plupart des irrégularités superficielles par électro-polissage et il reste très peu d'emplacements de formation de noyaux, où des gravillons fins à dimension située entre 74 et 100 microns, peuvent s'accumuler pour provoquer l'obturation du tamis.

Abstract: The invention relates to a method in mobile radio systems in which the responsibility for transmitting message information to a mobile station (MS 1 , MS 2 ) is handed over from at least a first base station transmitter (B ma ,B mb ) to at least a second base station transmitter (B na ,B nb ). 
     In accordance with the invention, the same radio channel is used, if possible, before and after the handover for transmitting message information to the mobile station. If the same radio channel can be utilised, the handover takes place without the mobile station being informed beforehand of the handover by a special signal or order or the like. 
     In digital mobile radio systems with digital transmission of message information by digital modulation of the radio signals, the transmission is preferably started from a second base station transmitter before the transmission is terminated from a first base station transmitter. During a transmission time substantially the same message information is transmitted to the mobile station from both at least one first and one second base station transmitter.

Abstract: Semiconductor devices comprising a semiconductor structure (D3) of parallel semiconductor layers on a semiconductor substrate (1), in which layers a mesa (12) is formed which comprises only a portion (D1) of the semiconductor layer structure (D3) find their application, for example, in optoelectronic devices in which the mesa (12) forms part of a semiconductor diode laser or a radiation waveguide. 
     During cleaving of such devices, for example for the formation of a mirror surface, damage often arises near the mesa (12), which is undesirable. The mesa (12), which projects from the device, is also easily damaged during further manipulation of the device. 
     According to the invention, the semiconductor layer structure (D3) comprises a sunken region (11) within which the semiconductor layer structure (D3) is at least partly recessed into the substrate (1), while the mesa (12) is positioned within the boundaries of the sunken region (11). As a result, the mesa (12) is also recessed at least partly, and thus at least partly protected. In addition, less damage occurs near the mesa (12) during cleaving. When the mesa (12) is entirely recessed, the device is in addition particularly suitable for upside-down final mounting. In a method according to the invention, a recess (11) is provided in the substrate (1) before the semiconductor layer structure (D3) and the mesa (12) therein are provided. This method is very simple and gives a high yield of devices having the required characteristics.

Abstract: An improved adaptive transmission pressure control in which cumulative adaptive corrections are stored in a multi-cell memory array, the cells being associated with specified contiguous ranges of a vehicle operating parameter, such as engine throttle position. Periodically determined adaptive correction amounts are applied to a selected cell (230) which includes the engine throttle setting measured at the initiation of the shift and to two or more cells (232-238) associated with contiguous engine throttle ranges. In this way, a relatively large number of cells may be employed to minimize approximation errors, while maintaining a cell-to-cell continuum of pressure correction values. In operation, an electro-hydraulic pressure regulator is controlled as a combined function of a predefined pressure command obtained from a normal table look-up and a cumulative correction amount obtained from the memory array.
